The wind is also an important agent in the pollination of Corn and aids some in orchard pollination. Plants having showy flowers depend upon insects for pollination and it is among these plants that attractive colors, secretions of nectar, and various structural arrangements, which are interpreted as adaptations to secure pollination, occur. The pollination of Fruit trees, Clovers, and Alfalfa is done chiefly by insects. (Fig. 56.) In experimental work, such as crossing. 11 Fig

Tomatoes, Corn, and Fruit trees, man himself often does the pollinating so as to have it under control. Kinds of Pollination. — On the basis of the relation of the stamen furnishing the pollen to the pistU pollinated, there can be different kinds of poUination. The transfer of pollen from the stamen to the pistil of the same flower is self-pollination, while the transfer to the pistil of another flower is cross-pollina- tion. Various relationships may occur in pollination. Thus the.
